My friend wants to swap a b16a1 into his crx. I will be helping him do this. As far as I know there is no modifications needed except for running the vtec to the ECU. If there are please tell me. We were going to do the B18b with upgraded mods but I currently read about cutting and welding and a whole bunch of other bullshit. I thought the swap was pretty straight forward. I had once heard that all you needed was a mount for the tranny and it would go right in. What's up que me in.
